Fisher CZ21 Underwater Multi-Frequency Metal Detector

The CZ-21 QuickSilver by Fisher® Research Labs is a trusted and reliable metal detector, known for its robust design and exceptional performance in both land and underwater treasure hunting. Built to withstand the toughest conditions, the CZ-21 is submersible up to 250 feet, making it ideal for detecting valuable metals on beaches, in saltwater, and freshwater environments. 

Featuring a 3-Tone Target-ID system, the CZ-21 offers clear audio distinctions for different types of metals: a low tone for iron, a mid-tone for pull tabs, foil, and most gold rings, and a high tone for U.S. coins, silver rings, and some gold rings. This allows users to easily identify and differentiate between various metal types without even looking at the display. 

The detector utilizes patented Fourier domain signal analysis with two deep-seeking, ground-compensating VLF signals operating at 5 KHz and 15 KHz. This dual-frequency system provides twice as much target information for accurate analysis and identification, ensuring that even the smallest and deepest targets are not missed. 

The CZ-21 offers two search modes: a silent-running, slow-motion Target-ID Mode and a hot, Auto-Tune Mode for all-metal searching. Additionally, the V.C.O. No-Motion Pinpointing feature makes it easy to locate targets precisely, as the audio tone increases in pitch and volume as the center of the coil approaches the target. 

Designed with user comfort in mind, the CZ-21 comes with a cushioned armrest, a soft foam grip, and a control housing that can be easily removed and hip-mounted. This makes prolonged use more comfortable and reduces fatigue, allowing for longer treasure hunting sessions. 

With its big-target alert, faint-target audio boost, and quick manual ground balance, the CZ-21 QuickSilver is a highly capable and user-friendly metal detector. Whether you're a professional diver, a beachcomber, or a land detectorist, the CZ-21 offers the performance and reliability needed to uncover hidden treasures in any environment. Experience the thrill of discovery with the CZ-21 QuickSilver from Fisher® Research Labs.
